The automated Unit Directory of Selected Reserve Medical Personnel assists the Joint Medical Readiness and Training Center (JMRTC) in planning the work of the mobile teams responsible for conducting the nonresident Combat Casualty Care Courses (4). The students are reserve component health care professionals from the four Military Services. The directory operates on personal computers. In addition to providing medical manpower information, it uses color graphics to display unit locations overlayed on road maps. Trip planning time has been reduced and C4 training is being offered to a wider audience. In this report, we discuss expansions to the directory that would be useful to JMRTC and other potential users. Two appendices are included, a users guide and software maintenance guide.
